Perfect for hoons, Youtubers and road racers with looking for bragging rights is this do-it-yourself G-force meter. The little box can measure acceleration and tilt on one axis. Attach it to your windshield and see what kind of acceleration and braking forces you can get with your car or turn it sideways and see how good your car is in a corner. We would hope whatever you drive would be able to do a little better than this techno-fiend of a creator in his Honda Civic. Follow the link to see the build process and spend about nine seconds deciding its easier to just buy one off the shelf. [PyroElectro via Gizmodo]
